Mögliche Peierls‐Verzerrung durch die Bildung von Re2‐Dimeren in den LaNiO2‐Typ Nitriden LnReN2 (Ln = Pr, Nd)

open access: yesAngewandte Chemie, Volume 138, Issue 5, 28 January 2026.
Diese Studie untersucht die Hochdrucksynthese von zwei neuen Perovskit‐verwandter Nitriden mit geordneten Anionen‐Fehlstellen, PrReN2 und NdReN2, welche im verzerrten LaNiO2‐Strukturtyp kristallisieren. Röntgen‐ und Neutronenbeugung zeigen eine strukturelle Verzerrung, die durch die Dimerisierung der Re‐Ketten verursacht wird, während Berechnungen der ...

Kovalente Aktivierung des C‐Typ Lektins DC‐SIGN

open access: yesAngewandte Chemie, Volume 138, Issue 3, 16 January 2026.
Wir stellen die ersten kovalenten Aktivatoren eines C‐Typ‐Lektins vor. Mithilfe orthogonaler funktioneller Assays, NMR, MS/MS und computergestützter Modellierung untersuchen wir die Mechanismen eines funktionellen „Electrophile‐first“‐Screenings gegen DC‐SIGN.

Animazione di corpi rappresentati, fra scienza e progetto

open access: yesDiségno, 2017
Molte pratiche progettuali odierne si concentrano sulla forma complessa esibendo superfici libere animate che ricalcano le altrettanto complesse geometrie e la struttura del corpo umano.

Pikosekunden‐Stabilisierung von übertragenen Ladungsträgern an plasmonischen Metall‐Molekül‐Grenzflächen

open access: yesAngewandte Chemie, Volume 138, Issue 1, 2 January 2026.
Ladungs‐ und Wärmeübertragungsprozesse zwischen plasmonischen Nanopartikeln und adsorbierten molekularen Monoschichten werden mittels ultraschneller Infrarotspektroskopie beobachtet. Die Analyse der Absorption freier Ladungsträger und der Schwingungssignale zeigt, dass überlaufende Ladungsträger stabilisiert werden, wodurch sich ihre Lebensdauer auf ...

A pan‐European citizen science study shows population size, climate and land use are related to biased morph ratios in the heterostylous plant Primula veris

open access: yesJournal of Ecology, Volume 114, Issue 1, January 2026.
A large‐scale citizen science study involving thousands of cowslip (Primula veris) observations from all over Europe revealed an unexpected prevalence of S‐morphs over L‐morphs, which was influenced by climatic as well as land use factors. Furthermore, general morph ratios were often unbalanced with the strongest shifts occurring in smaller populations.

Space‐Time Boundary Elements on Graded Meshes for 3D Elastodynamics

open access: yesInternational Journal for Numerical Methods in Engineering, Volume 126, Issue 20, 30 October 2025.
ABSTRACT The solution to the elastodynamic equations in the exterior of a polygonal or polyhedral domain or a screen exhibits singularities at corners and edges. This paper presents a space‐time boundary element method in 3D on algebraically graded meshes to resolve these singularities, based on recently obtained error estimates for the weakly singular
